Thunderstorms Likely Across Mountains, Antelope Valley

LOS ANGELES (CBS) — A thunderstorm moving up the coast through Orange County Saturday dropped pea-sized hail on several cities southeast of Los Angeles.

"The clouds that constitute a thunderstorm go way up high into the atmosphere and do get well above the freezing layers so you can get hail even in a hot, summer day," said Meteorologist Miguel Miller with the National Weather Service.

Miller says the storm clouds followed a path along the 405 from Santa Ana up into Westminster and Garden Grove.

Although a quick strike in Orange County, the storm's activity appears to be different in Los Angeles and Ventura counties.

"Later this afternoon, we'll start seeing a development over the mountains and it could spill over into the valleys later," Meteorologist Kurt Kaplan with the NWS said. "But to say the least, we will get some thunderstorms across the mountains and the Antelope Valley and possibly into the valleys and coastal areas later today," Meteorologist Kurt Kaplan with the NWS said.

Kaplan tells KNX 1070's Ed Mertz that a flash flood watch is in effect for the mountains and interior regions of LA and Ventura counties through this evening.
